Thanks for your feedbacks. We will take this locktite into consideration.

Firmware upgrade to 3.05 fixed the connection brake problem and both works ok now.
Great job.We are so glad to hear this!

Hello again,

I received my TTL board from futurelec today, and before I embark on my upgrade, I was looking at my old iMax interface board (Bantam B6 USB logger). It detects in the "Updater" program as Comm10, so I'm wondering if anyone else has modded this MUCH smaller device to fit inside the iCharger? One side of this little USB device has a servo type 3pin lead.

Any thoughts? Is it possible to use it instead of the TTL board?

Hi guys!

I would like to upgrade my 1010B to the latest FW, but I don't have much electronics skills, and I'm afraid I will get lost in the process. Does anybody have the pictures (and time) to make a "Do it yourself FW upgrade for dummies" walkthrough? I'm sure this will be helpful to a lot of users out there!

Thanks!

Lars

Hey Junsi,

Just a question.....Why does my iCharger power up when i connect a lipo to the "Output"?

Oh wait, it doesn't charge now......what the?

If i enter into balance mode as i have before, the charger resets....overloads my power supply, and feeds from the LiPo


I have left the charger off for 5 minutes now, and still the same. I'm not game to hook it to my car battery incase something goes BANG!

Heh, not much point even opening the unit now.....lol. Poor old charger is not functioning very well.

It seems that mine likes to power on using the Output section for some reason.... It went haywire after I tried putting a pack in storage mode. It did a reset, (beep, firmware display), now won't charge/dischage at any rate....

YEEHAW!
I just recieved my first iCharger from Hobbycity!
After checking that it powers up properly, I decided to immediately upgrade it to 3.05. After a brief period of "not find device" frustration, I decided to swap RX and TX, and it worked. I used a USB to serial converter, and a serial to TLL converter, quite a contraption

Now I will check how it works.

Junsi, I also noted that the PCB screws are not very tight, and some are almost loose. You definitely should consider using loctite, as previously suggested.

Edit: So far, so good.

Some things I noticed need to be improved:
1) The inner diameter of the charging sockets. Urgently! It is like 3.8mm or so. But it should be not less than 4mm, as the standard Banana Connector has 4mm diameter. I had to drill the sockets to 4mm
This should definitely not be required!

2) Whenever the charger toggels between two different texts on the display, like "confirm/cancel" when one starts a charge, the toggling frequency is too high. One has a hard time reading the text like this. A toggling frequency of 0.5Hz would be more convenient, and less stressful to read.

3) One should be able to start the foam cut program with the external switch of the cutting wire open. So the current flow will only depend on the external switch. When one wants to start the program now, with the switch open, a "connection break" error message comes. Instead, the program should start, so that the current will flow when the external switch is closed.

4) I noticed the same thing as BlueAngel2000 when comparing the iCharger values with the values of my WattsUp wattmeter: The current displayed on the WattsUp is lower (9.6A with 10A charge current), and the capacity was also 5% lower than what was displayed on the charger. However, the WattsUp may well not be the most precise meter ever made.
The display is very good! The contrast is high, and it is very easy to read. Well done!

Apart from that, I am quite satisfied with the charger. The overall appearance is good, the metal parts are good quality and fit nicely, and the PCB is also done well. The mechanical feeling of the buttons is ok, but they could stick out of the case about 1-2mm, this would feel better IMHO.

Right now, I charge 2 3s 2200 Hextronic packs in series in the slow balance mode. Let's see how this works out.

Edit: It worked out well. All cells were within 10mV of each other. 4 cells were at 4.18V, and 2 were at 4.19V.

Cheers,

Julian

Hi,

Sorry but I'm just newb in this charger stuff...I bought the iCharger 1010b mostly because of good reviews and capability. I don't know nothing about chargers and betteries other than lipo can be dangerous and I think I'm carefull. I'm happy with the icharger, was confused first because like couple other people did not know you had to connect the output leads to the lipo else you get voltage error not expplained in the manual, and when you come from basic esky cheap charger you just don't know... not mentioning the fear factor to make mistakes with lipo.

Anyway I'm happy and feel safe with this charger as I can charge single pack of what ever I want. The only complain is that all this things is to complex for me! and wish it was a bit more simple...I curretnly do not use the product to its full possibilites that's my fault an only complain is that it is not explained for newb....and that is sad, I like to be able to balance charge 3x2s... but I don't know how to make leads, if it should be parallel or serie connections what is the advantage paralle or serie how to do etc... I read all the post on the icharger, well half of it from the anouncement to about the midle, I saw schematics also picture etc...but just don't know how to charge 3x2s with this charger.

Can someone explain for NON electronic or battery specialist :-) a picture would be great with simple schema ...just don't understand the schema posted sofar, don't want to short batteries and also the fact it can be dangerous makes me be very cautious.

Again very interesting post, I get to learn things definitively, just new here and need some basic explanation to fully use that charger... I think despite the great capability of the 1010b explanation in manual and how to take FULL advantage of the product for beginers would certainly make the product even more successfull : ie commecial charging leads etc... I saw many post of many confused users about chargers in general.

Thanks for any explanation to take fully adavantage of this charger, if there would be commercial leads or what ever you want to call it to charge 3x2s / 3x3s with simple diagram I would buy the leads.

Now I am charging a 2s 900mAh Mystery LiPo. Before, I deliberately discharged 50mAh from one cell, to give the balancer some work to do.

Suggestion for improvement:

LiPo monitor mode: It should not be neccessary to enter the cell count here. If a pack is connected with the balance plug, the charger should be able to know by itself the cell count. As the monitor mode neither charges nor discharges, it can do no harm to the battery. Therefore, safety measures concerning this mode are superfluous. Likewise, the time the "enter" button needs to be pressed to enter this mode, should be reduced from 3 to 0.5 sec, as accidently hitting this button can cause no harm.

Questionmark:

First, build a charging cable to connect the battery cables as shown at the top of this image:
http://www.hock-modellbau.de/bilder/BleiAkkuGrafik.jpg

Then you take the balance cable of the pack, where the necative contact is connected to the charger. This balance cable is plugged in at the left side of the balance board (the left side is the side where "adapter" is written in this image: http://www.rcgroups.com/forums/attac...mentid=1869453 )
The balancer plug from the pack from the middle is connected to the balance port next to the one from the first pack, and so on.

Cheers,

Julez

Hi!

While charging the 2s Pack with 1A, I noticed slight current fluctuations. Every now an then, the current was reduced to 0.95V, 0.98V or something in the neighborhood. I also noticed this behaviour on my 4s A123 pack.

At the 2s Lipo, the total voltage was around 8.2V, and the cell voltage was 4.08V. Thus, a high voltage of a cell cannot be the reaso for the charger to reduce the current.

Cheers,

Julez

Things are not looking good at the moment here

I had a row of problems with my iCharger:

First, I wanted to charge a 8s A123 pack; I set the current to 10A.
When I tried to start the charge, a strange humming could be heard from my 30A power supply, and its fan started to turn. This is totally strange, as the fan is normally temperature controlled. Could it be, that there was some strange backcoupling from the iCharger? This strange behaviour lasted for 2-3sec, then the error message "connection break down" was displayed.
I tried it several times, no success.
This is strange, as all other charges I made so far worked fine from the same power supply.
I tried again with a different 6.5A power supply, a little sound like whistling or humming could be heard, but the same result, it did not work.
Then I tried it with a 12V lead acid battery, and 3A charge current, and the charge worked.
I stopped the charge, and connected the lead acid battery to the power supply, and reconnected the iCharger to the power supply, too.
I started the charge with 10A, and it worked. Now I disconnected the lead acid battery, and the charge continued
But only for a short time. A little "pftz" sound could be heard, and the charger rebooted.
From now on, every time I tried to start a charge, the charger rebooted, as if it was briefly disconnectd from the power supply. After some tries, a little "pftz" sound could be heard again, and from now on, every time I tried to start a charge, regardless which battery, I got the "connection break down" message.

I have checked the PCB, but I cannot find any blown components.

Junsi, I need your help

Cheers,

Julez
